Quizplus · Accepted Answer

The safety fuse is designed to interrupt the flow of current in the circuit if the current exceeds a safe level, and it does so by heating up and melting. Therefore, it needs to be connected in series with the circuit so that all of the current flowing through the circuit also flows through the fuse. If the fuse were connected in parallel with the circuit, it would not necessarily limit the current through the circuit and could fail to protect the circuit from overloading.
